DICARBOXYLIC ACID FERMENTATION PROCESS
FIELD OF THE INVENTION
The present invention relates to a process for the production of dicarboxylic
acids. In
particular, it relates to the production of dicarboxylic acids by fermentation
of yeast.
BACKGROUND OF THE INVENTION
Dicarboxylic acids, such as malic acid and succinic acid, are important
compounds which
are used in the food industry for the preparation and preservation of food, in
the medical
industry for the formulation of medical products and for other industrial
uses, such as
monomers for (bio) polymers. Dicarboxylic acids can be produced by
petrochemical
processes or fermentation based processes, by either bacteria or fungal cells.
Bacteria that have been studied for improved succinic acid production are for
example E.
cog, Mannheimia sp., Actinobacillus sp. or Corynebacteria. A disadvantage of
bacterial
dicarboxylic acid fermentation processes is that such processes need to be
carried out at
high pH and neutralizing agents are needed to maintain the pH at a desired
value. In
addition, neutral pH processes require sterile process conditions, increasing
the
production costs further.
In contrast to bacteria, fungal cells are able to grow at low pH values and do
not require
strictly sterile process conditions, making fungal cells an attractive
alternative for the
production of dicarboxylic acids.
In W02009/065780 recombinant fungal cells such as yeast and filamentous fungus
were
developed for the production of dicarboxylic acids, resulting in increased
production
levels of succinic acid and fumaric acid.
W02008/14462 shows that the addition of carbon dioxide of up to 10 v/v13/0
increased
production levels of malic acid and succinic acid by a recombinant yeast cell,
but higher
concentrations of carbon dioxide did not further increase dicarboxylic acid
production
levels.
Despite the improvements made with genetically modified fungal cells for
producing
dicarboxylic acids, there is a need for further improving dicarboxylic acid
production by
fungal cells.
SUMMARY OF THE INVENTION

70500-282
2
The present invention relates to a process for producing a dicarboxylic acid,
comprising
fermenting a recombinant fungal cell in a suitable fermentation medium, which
comprises a
carbon dioxide concentration ranging between 25 and 75 v/v% of total gas
present in the
fermentation medium and producing the dicarboxylic acid. Surprisingly, it was
found that the
yield of dicarboxylic acid (g/g sugar) in the process according to the present
invention was
increased significantly compared to a process comprising carbon dioxide
outside of the
concentration range of the invention.
Another advantage of the process according to the invention was that the
specific productivity
(g dicarboxylic acid / g sugar / h) was also increased significantly as
compared to a process
for the production of dicarboxylic acid comprising carbon dioxide outside of
the concentration
range of the invention.
In an embodiment, there is provided process for producing a dicarboxylic acid
comprising
fermenting a recombinant yeast in a suitable fermentation medium, wherein
carbon dioxide in
a concentration of 25 to 75 v/v% of total gas present in the fermentation
medium is used to
increase dicarboxylic acid production.
Definitions
The terms "dicarboxylic acid" and "dicarboxylate", such as "succinic acid" and
"succinate"
have the same meaning herein and are used interchangeably, the first being the
hydrogenated
form of the latter.
The term fermenting or fermentation as used herein refers to the microbial
production of
compounds such as alcohols or acids from carbohydrates.
A recombinant fungal cell according to the present invention is defined herein
as a cell which
contains a disruption of a gene or contains, or is transformed or genetically
modified with a
nucleotide sequence that does not naturally occur in the fungal cell, or it
contains additional
copy or copies of an endogenous nucleic acid sequence. A wild-type fungal cell
is herein
defined as the parental cell of the recombinant cell.
Disruption, or deletion or knock-out of a gene means that part of a gene or
the entire gene has
been removed from a cell, or a gene has been modified such that the gene is
not transcribed
into the original encoding protein.
CA 02771162 2017-01-30
70500-282
2a
The term "homologous" when used to indicate the relation between a given
(recombinant)
nucleic acid (DNA or RNA), gene or polypeptide molecule and a given host
organism or host
cell, is understood to mean that in nature the nucleic acid or polypeptide
molecule is produced
by a host cell or organisms of the same species, preferably of the same
variety or strain.
The term ''heterologous" when used with respect to a nucleic acid (DNA or RNA)
or protein
refers to a nucleic acid, gene or protein that does not occur naturally as
part of the organism,
cell, genome or DNA or RNA sequence in which it is present, or that is found
in a cell or
location or locations in the genome or DNA or RNA sequence that differ from
that in which it
is found in nature. Heterologous nucleic acids or proteins are not

endogenous to the cell into which it is introduced, but have been obtained
from another
cell or synthetically or recombinantly produced.
Sequence identity is herein defined as a relationship between two or more
amino acid
(polypeptide or protein) sequences or two or more nucleic acid
(polynucleotide)
sequences, as determined by comparing the sequences. Usually, sequence
identities or
similarities are compared over the whole length of the sequences compared. In
the art,
"identity" also means the degree of sequence relatedness between amino acid or
nucleic
acid sequences, as the case may be, as determined by the match between strings
of
such sequences.
Preferred methods to determine identity are designed to give the largest match
between
the sequences tested. Methods to determine identity and similarity are
codified in publicly
available computer programs. Preferred computer program methods to determine
identity
and similarity between two sequences include BLASTP and BLASTN, publicly
available
from NCB! and other sources (BLAST Manual, Altschul, S., et al., NCB! NLM NIH
Bethesda, MD 20894). Preferred parameters for amino acid sequences comparison
using
BLASTP are gap open 11.0, gap extension 1, Blosum 62 matrix.
There are known methods in the art for overexpression of genes encoding
enzymes. A
gene encoding an enzyme may be overexpressed by increasing the copy number of
the
gene coding for the enzyme in the cell, e.g. by integrating additional copies
of the gene in
the cell's genome, by expressing the gene from a centromeric vector, from an
episomal
multicopy expression vector or by introducing an (episomal) expression vector
that
comprises multiple copies of one or more gene(s). Preferably, overexpression
of a gene
encoding an enzyme according to the invention is achieved with a (strong)
constitutive
promoter.
Suitable promoters in fungal cells are known to the skilled man in the art.
Suitable
promotors may be, but are not limited to, TDH1, TDH3, GAL?, GAL10, GAL1, CYC1,
HIS3, ADH1, PH05, ADC1, ACT1, TRP1, URA3, LEU2, EN01, TPI1, A0X1, PGL, GPDA
and GAPDH. Other suitable promoters include PDC1, GPD1, PGK1, and TEF1.
A gene encoding an enzyme may be ligated into a nucleic acid construct, for
instance a
plasmid, such as a low copy plasmid or a high copy plasmid. The fungal cell
according to
the present invention may comprise a single copy, but preferably comprises
multiple
copies of a gene, for instance by multiple copies of a nucleotide construct.
A nucleic acid construct may be maintained episomally and thus comprises a
sequence
for autonomous replication, such as an autonomously replicating sequence and a
centromere (Sikorski and Hieter ,1989, Genetics 122, 19-27). A suitable
episomal nucleic
acid construct may e.g. be based on the yeast 2p or pKD1 plasmids (Gleer et
al., 1991,
Biotechnology 9: 968-975), or the AMA plasmids (Fierro et al., 1995, Curr.
Genet.

29:482-489). Alternatively, each nucleic acid construct may be integrated in
one or more
copies into the genome of the fungal cell. Integration into the cell's genome
may occur at
random by non-homologous recombination but preferably, the nucleic acid
construct may
be integrated into the cell's genome by homologous recombination as is well
known in
the art.
DETAILED DESCRIPTION OF THE INVENTION
In one embodiment the process for producing a dicarboxylic acid, comprising
fermenting
a recombinant fungal cell in a suitable fermentation medium comprises a carbon
dioxide
concentration ranging between 25 and 75 v/v%), for example between 35 and 65
v/V)/0, or
between 40 and 60 v/vc)/0 of total gas present in the fermentation medium.
The carbon dioxide present in the fermentation medium may be added to the
medium in
the form of gaseous carbon dioxide in a gas flow, for instance a gas flow
comprising
carbon dioxide at a concentration between 25 and 75 v/vc)/0. Suitable
concentrations of
carbon dioxide in a gas flow may range as described herein above.
The carbon dioxide may also be present in the fermentation medium by the
addition of
carbonate or bicarbonate salt, for instance calcium carbonate or calcium
bicarbonate.
Usually carbon dioxide is also formed during fermentation of a recombinant
fungal cell in
the process of the invention.
As used herein the term total gas in the fermentation medium comprises
dissolved and
not dissolved gas. Total gas in the fermentation medium comprises carbon
dioxide and
oxygen, and usually further comprises nitrogen and may comprise any gas
molecules
produced by fermenting the fungal cell, or added to the fermentation medium by
e.g.
sparging a gas flow through the fermentation medium.
It was found advantageous that total gas in the fermentation comprises oxygen,
providing
the recombinant fungal cell to generate energy via oxidation. Preferably, the
total gas
comprises low amounts of oxygen.
Preferably, the process as disclosed herein is carried out under aerobic
conditions,
preferably under microaerophilic conditions or oxygen limited conditions.
Microaerophilic
or oxygen limited conditions are reflected in the oxygen uptake rate (OUR).
For example,
the process described herein comprises supplying oxygen at an oxygen uptake
rate
lower than 8.0 mmol oxygen/L/hour and above 0.01 mmol oxygen/L/hour.
In one embodiment the OUR is lower than about 6.0 mmol oxygen/L/hour,
preferably
lower than about 5.0, 4.0, 3.0, or 2.0 mmol oxygen/L/hour, more preferably
lower than
about 1.0, or 0.5 mmol oxygen/L/hour, preferably above 0.01 mmol
oxygen/L/hour. It was
found that oxygen-limited conditions resulted in an increased yield of
dicarboxylic acid in
the process according to the present invention.
CA 02771162 2012-02-14
WO 2011/023700 PCT/EP2010/062345
In one embodiment the fermentation medium in the process disclosed herein
comprises a
carbon source, preferably a carbon source selected from the group consisting
of glucose,
fructose, galactose, xylose, arabinose, sucrose, lactose, maltose, raffinose
and glycerol.
The fermentation medium usually comprises a nitrogen source such as ammonium
or
5 ureum. The fermentation medium may comprise biotin.
In one embodiment in the process for producing a dicarboxylic acid of the
present
disclosure, a recombinant fungal cell overexpresses a gene encoding a
phosphoenol
pyruvate (PEP) carboxykinase. Any PEP- carboxykinase catalyzing the reaction
from
phospoenol pyruvate to oxaloacetate (4.1.1.49) may be suitable for
overexpression in a
fungal cell. A fungal cell may overexpress a heterologous PEP carboxykinase,
such as a
PEP carboxykinase derived from Escherichia coli, Mannheimia sp.,
Actinobacillus sp., or
Anaerobiospirillum sp., more preferably Mannheimia succiniciproducens,
Actinobacillus
succinogenes, or Anaerobiospirillum succiniciproducens. In one embodiment a
gene
overexpressing a PEP carboxykinase in a fungal cell in the process herein
disclosed is
expressed in the cytosol. In one embodiment a fungal cell of the present
disclosure
overexpresses a gene encoding a PEP-carboxykinase comprising an amino acid
sequence that has at least 70, 80, 90, 95, 97, 98, 99 or 100% sequence
identity with the
amino acid sequence of SEQ ID NO: 6.
It was found advantageous that a recombinant fungal cell overexpresses a PEP-
carboxykinase in the process for producing of a dicarboxylic acid in the
presence of 25 to
75 v/V3/0 carbon dioxide, since overexpression of PEP carboxykinase resulted
in an
increased fixation of carbon dioxide, i.e. the conversion of phosphoenol
pyruvate (03) to
oxaloacetate (C4), resulting in a higher yield of dicarboxylic acid.
In another embodiment in the process for producing a dicarboxylic acid of the
present
disclosure a recombinant fungal cell overexpresses a pyruvate carboxylase
(PYC), that
catalyses the reaction from pyruvate to oxaloacetate (EC 6.4.1.1). Preferably
the
pyruvate carboxylase is active in the cytosol upon expression of the gene.
Preferably, an
endogenous or homologous pyruvate carboxylase is overexpressed.
In another embodiment, a recombinant fungal cell in the process for producing
a
dicarboxylic acid disclosed herein comprises a disruption of a gene encoding
an enzyme
of the ethanol fermentation pathway. A gene encoding an enzyme of an ethanol
fermentation pathway, may be pyruvate decarboxylase (EC 4.1.1.1), catalyzing
the
reaction from pyruvate to acetaldehyde, or alcohol dehydrogenase (EC 1.1.1.1),
catalyzing the reaction from acetaldehyde to ethanol. Preferably, a fungal
cell in the
process as disclosed herein comprises a disruption of one, two or more genes
encoding
an alcohol dehydrogenase. In the event the fungal cell is a yeast, e.g.
Saccharomyces
CA 02771162 2012-02-14
WO 2011/023700 PCT/EP2010/062345
6
cerevisiae, the Saccharomyces cerevisiae preferably comprises a disruption of
an alcohol
dehydrogenase gene adhl and / or adh2.
The process for producing a dicarboxylic acid of the present disclosure was
found
particularly advantageous for cells comprising a disruption of a gene encoding
an
enzyme of the ethanol fermentation pathway. This resulted in an increase of
dicarboxylic
acid yield and at the same time cells lacking the ability to produce energy in
the form of
ATP by ethanol fermentation, were able to fulfill the requirement of ATP
formation via
oxidation.
In another embodiment, a fungal cell disclosed herein comprises a disruption
of a gene
encoding a glycerol-3-phosphate dehydrogenase. Disruption of a gene encoding a
glycerol-3-phosphate dehydrogenase usually results in a reduced formation of
glycerol. In
the event the fungal cell is a yeast, such as Saccharomyces cerevisiae, the
fungal cell
preferably comprises a disruption of a gpdl gene.
In one embodiment the recombinant fungal cell further overexpresses a gene
encoding
an enzyme selected from the group consisting of a malate dehydrogenase, a
fumarase, a
(NAD(H)-dependent fumarate reductase, and a dicarboxylic acid transporter
protein.
Preferred embodiments of these enzymes are as described herein below.
In one embodiment a fungal cell of the present disclosure further
overexpresses a gene
encoding a malate dehydrogenase (MDH) active in the cytosol upon expression of
the
gene. A cytosolic MDH may be any suitable homologous or heterologous malate
dehydrogenase, catalyzing the reaction from oxaloacetate to malate (EC
1.1.1.37).
Preferably a fungal cell comprises a gene encoding a malate dehydrogenase that
has at
least 70, 80, 90, 92, 94, 95, 96, 97, 98, 99 or 100% sequence identity with
the amino acid
sequence of SEQ ID NO: 9.
In another embodiment a fungal cell of the present disclosure further
overexpresses a
gene encoding a fumarase, that catalyses the reaction from malic acid to
fumaric acid
(EC 4.2.1.2). A gene encoding fumarase may be derived from any suitable
origin,
preferably from microbial origin, for instance a yeast such as Saccharomyces
or a
filamentous fungus, such Rhizopus olyzae. A fungal cell of the present
disclosure may
overexpress a nucleotide sequence encoding a fumarase that has at least 70%,
or, 80,
90, 92, 94, 95, 96, 97, 98, 99, 100% sequence identity with the amino acid
sequence of
SEQ ID NO: 8. In one embodiment the enzyme catalysing the conversion of malic
acid to
fumaric acid is active in the cytosol upon expression of the nucleotide
sequence. It was
found that cytosolic activity of fumarase resulted in a high productivity of a
dicarboxylic
acid by the fungal cell.
In another embodiment the fungal cell overexpresses any suitable heterologous
or
homologous gene encoding a NAD(H)-dependent fumarate reductase, catalyzing the
CA 02771162 2012-02-14
WO 2011/023700 PCT/EP2010/062345
7
reaction from fumarate to succinate (EC 1.3.1.6). The NADH-dependent fumarate
reductase may be a heterologous enzyme, which may be derived from any suitable
origin, for instance bacteria, fungi, protozoa or plants. A fungal cell of the
present
discolsure comprises a heterologous NAD(H)-dependent fumarate reductase,
preferably
derived from a Trypanosoma sp, for instance a Trypanosoma brucei. In one
embodiment
the NAD(H)-dependent fumarate reductase is expressed in the cytosol. The
fungal cell
may overexpress a gene encoding a NAD(H)-dependent fumarate reductase that has
at
least 70, 80, 90, 92, 94, 96, 98, or 100% sequence identity with SEQ ID NO:7.
In another embodiment the fungal cell overexpresses a gene encoding a
dicarboxylic
acid transporter protein, for instance a malic acid transporter protein (MAE).
A
dicarboxylic acid transporter protein may be a homologous or heterologous
protein. A
dicarboxylic acid transporter protein may be derived from any suitable
organism, for
instance from Schizosaccharomyces pombe. A fungal cell as disclosed herein may
comprise a dicarboxylic acid transporter protein which has at least 70, 80,
85, 90, 95, 99
or 100% sequence identity with SEQ ID NO: 10.
In one embodiment the fungal cell is a yeast or a filamentous fungus, for
instance

cerevisiae.
Any suitable dicarboxylic acid may be produced in the process as described
herein, for
instance succinic acid, fumaric acid or malic acid, for instance succinic
acid.
The process for the production of a dicarboxylic acid of the present
disclosure may be
carried out at any suitable pH between 1 and 8. The pH in the fermentation
broth may be
between 2 and 7, preferably between 3 and 5.

In another embodiment the process comprises recovering the dicarboxylic acid
from the
fermentation medium by a suitable method known in the art, for instance by
crystallisation, ammonium precipitation or ion exchange technology.
In one embodiment, the dicarboxylic acid that is prepared in the process
according to the
present invention is further converted into a pharmaceutical, cosmetic, food,

0.33 vvm was applied, with varying percentages of CO2 in the gas mixture.
During the cultivation of 90 hours growth occurred to a typical biomass
concentration of 8
g/L.
1.2.2. NMR analyses
Dicarboxylic acid concentrations in the fermentation supernatant were
determined by
means of NMR spectroscopy.
3 ml broth was centrifuged for 10 min at 4500 x g. Approximately 500
microlitres of
supernatant were accurately weighed to a head space vial. To each sample 0.5
ml of pen
CA 02771162 2012-02-14
12
buffer C-2696 (containing 5.62 mg/ml maleic acid) was added. The samples were
capped
and cooked for about 10 minutes in a water bath (and in oil bath in the
control sample
CF292706-11 and CF292706-12) at 100 C. The samples were lyophilized, the
residue
was dissolved in 1 ml D20.
The spectra were recorded at a proton frequency of Bruker DRX 360 MHz at a
probe
temperature of 300 K. The quantitative measurements were performed with pulse
program zg, excitation pulse from 30 - 90 degrees and a relaxation delay of
40s.
Figure 1 shows that a CO2 concentration increasing to about 50 v/v% resulted
in an
increased yield Yp. (g/g) of succinic acid and increased yield of malic acid
(MA) plus
succinic acid (SA) of about 10 to 30% as compared to a CO2 concentration of 10
v/v%.
An overall yield of SA + MA of 0.49 g/g was achieved when applying 50 v/vc/c,
CO2,
whereas 10 viv% CO2 resulted in a yield of 0.36 g/g SA + MA. The yield of SA
+MA
without the addition of 002 during the fermentation was 0.23 g/g.
Likewise the specific productivity qp (g/g/h) increased at higher CO2
concentrations
(Figure 2). A concentration of 50 v/v /0 CO2 resulted in an increased specific
productivity
of SA + MA (qpsAtmA) of 0.047 g/g/h compared to 0.039 g/g/h using 10 v/v /0
002.
Conclusion
The results show that carbon dioxide concentrations of between 25 and 76
v/V3/0 had a
positive effect on the yield and specific productivity of a dicarboxylic acid
(succinic acid
and malic acid) by a recombinant fungal cell, such as a recombinant
Saccharomyces
cerevisiae.
